T0 all 'whom it muy comfy-n Be it'known that l, tlirnis'rran M. Snor--TEN, citizen 'of-the United States7 residing have invented certain newand useful lmproveinents in ll'lultiple Stanchions; and I do herebydeclaretlic following to be a full. clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use l the same, reference being` had to theaccompanying drawings. and to let-ters or figures of reference markedthereon. which form a part of this specilication.

fThis invention relates to multiple'stanchions, and'inore particularlyto that'class of multiple stanchions adapted to be controlled by acommon mechanism, so that all of the stanchions may be operatedsimultaneously.

The object of this invention is to provide a vmultiple stanchion adaptedto be durable, useful and capable of beingy adapted to any building'.

il further object of thisv invention is to straining' devices of whichmay be simultaneously operated to restrain or 'tree an animal, or inwhich any desired number of the restraining devices'proper inaT be ac-`tuated, or remain inoperative.

A further object of the invention is to provide a stanchion adaptedtofacilitatc the housing of. .a number' o'll animals by eliminating theusual drawbacks of such devices. p p

With these and other lobjects in View, this invention consists-inthepeculiar construetion. and combination oic the parts ot a multiplestanchion as hereinafter described and more particularly1 pointed ont inthe ap' pended claims.

tieferring to the drawings wherein similar reference numerals indicatesimilar parts` wherever used, Figure l is a perspective view of themultiple stanchion. Fig, 2 is a l'ront elevation ot one of the stanchionunits. Fig. 3 is a vertical section on line 3 3, Fito'. Q. Fig. t is adetail isection through the lower part of the restraining deviceshcnving the spring'. Fig'. 5 is a dctailisection through one ot theguards showingthe spring'. G is a vertical section on line o-i (ilt Fig.Q.

lteterei'ice numeral 7 represeifits aA sill ot concrete -erthe likeformed on the Hoor-ofa. stable. Secured by bolts or embedded into thesill are a plurality`- of upright-s S preferably formed of piping` andhaving at their upper ends a flattened portion 9. lleloiv the tlattenedportion 9, the uprights are provided with threaded 'lsliaped nipples l0,which receive additional piping l1. adapted to define the differentstalls as 4shown in Fig'. l.

irdjaeent the beginning of the flattened portion is anon-rotatable shaft1Q, which is prevented from movement in anyY direcwheel t3, and adaptedto be controlled by a pawl 1S. mountedoii a bracket 19. lt will thus beseen that a` movementot' the handle ll will cause lthe cog-wheel 13 torotate the cog-Wheel 17J which will rotate the `shaft l5,` subjectto theaction ot the pawl 1S. ASecured to the shaft 15, and rotating' therewithare collars 20-Q0. lVound around the collars 2G-'20 and -tastened at oneend thereto are chains 21h02. the purpose ol which will he hereii'iatterset torth. Mid'- Walv between the nprio'hts the shaft 13. is Iprovidedwith two chains 29e-:2l which are Wound around the shat't 15. and thenpass downwardly through a tube 25. placed transversely through the shaftl2. The purpose ot these chains will he hereinafter de scribed.

Pivotally supported to the sill T by a chain 2li is a restrainingYdevice or stair eliion composed ot' two pivotallvY connected (at 26')bow-shaped sections 2T-QS. which are adapted to be held apart at theirupper ends 295l0 b v means of a. leal spring 3l. inserted above thepivot (see Fig: l.) The chains 'lwl-l are connorted to the upperportions 9 2() ot" thc stanchion. as at The chains are so arranged thatwhen they are wound np upon the sha lit. 1.5, they bring' the partsQT--QS ot the stanchioii together against' the action of the spring' 31,by

means ot the inward pull upon theparts 29- O, causing said parts to movefrom the position shown in dotted' lines 272-28 and Y 25) 30 shown-in-Fig. 2. The ull eX- 36-37 are joined by a pivoted yoke member 38,which bears slidably upon'the upper sur'- face of the-shaft 12. Placedwithin the bracket 33'is a leaf spring 39, which bearsl against theupright 8 and the members 35 and forces themembers'35'outwardly and 'vaway from the upright 8 toward the center' of the shaft 12, the member38 sliding along the shaft 12.

The; chains 21-22 heretofore described are wound about the rotatableshaft l5, and

25 pass downwardly under pulleys 40 supported by'brackets 41, upon theuprights S. From this point the chains run inwardly and are fastened at21-22 tothe yokeI members 38-38 in such a manner that when so the chains21-29 are wound ont-he shaft 15, the member 35 takes the position shownin full lines in Fig. 2. ,By rotating the shaft 15'to close thestanchions Q7 28 the chains controlling the members will also be 35wound up and will cause the members 35 to be drawn toward the upright 8against the action ofthe spring 39 and will come to restat a point abouthalf-way between the stanchions and the uprights, Jthis posi- 40 tionbeing regulated by the length of the chain. The function of thesemembers 35 is to form a guard uponeach side of the stanchions topreventan animal :from inserting its head into the space between the stanchionsand 'the uprights.

When the stanchion is in an open position the guards take the positionshown in dotted lines 35-35 in Fig. Q due to the spring forcing themembers outwardly.

'50 Should it be desired to leave a stanchien in closed position toconfine an animal, while the other stanchions are opened, there isprovided a pin 42, which is 'inserted through the links of the chains23-2-1 so that the pin .55 will bear against the upper part of the tube25, thus preventing further movement of the stanchion members 27 #128,wh ile the other stanchions are free to move. By rotating the shaft l5,the chains will be wound or R0 unwound upon the shaft 15, thus actuatingthe guards andthe stanchion members of the several restraining units,

Considerable variationof the specific ectails of this invention may beresorted to -without departing from the spirit thereof.
